The door to the Wizard's Tower is locked until you have access to the Community Center and have read the golden scroll in the Crafts Room.

Basement Room

After reaching four hearts with the Wizard, players will gain access to a basement where they can change the appearance they set at character creation. The Shrine of Illusions requires an offering of 500g each time it is used.

In late game, after players complete the quest Goblin Problem to gain passage to the Witch's Hut a teleportation rune will activate in the basement, allowing free passage between the basement room and the Witch's Hut anytime.

Buildings

After retrieving the Wizard's magic ink he'll make some unique buildings available for sale. These buildings will be conjured by him, requiring no build time. All are very expensive, and intended to better quality of life for end-game players.

To summon buildings interact with the magic book inside tower. This construction menu can move both conjured buildings and those constructed by Robin.
